7.1 Filling and venting procedure
Carefully refill and vent the pipe system. The pump rotor
space will be automatically vented after a short operating
period. Short term dry-running will not harm the pump. If
however, a direct venting of the rotor space becomes
necessary. proceed as follow :
- Switch off the power supply to the pump.
- Close the discharge isolating valve.
- Remove rear end coverplat (item 8).
- Carefully open the vent plug (item. 9) with a SW5 key.
Depending on temperature of the water, hot water or
flash vapor may erupt. Grave risks of scalding.
- Protect electrical parts from possible water spary.
- Switch on the pump.
- Close vent plug again after approximately 15 to 30
seconds.
- Re-open isolating valve.
- Rotation check (for only three-phase motor) : good
rotation direction when green running light.
